ADJUSTABLE DISPLAY-RACK.

SPECIFICATION forming part of Letters Patent No. 691 ,484, dated January 21, 1902.

Application filed July 24, 1901- To all whom it may concern.-

Be it known that I, CLARENCE E. PERRIN, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Adjustable Display-Racks, of which the following is a specification.

The objects of my invention are to provide an adjustable display-rack especially adapted for use in supporting boxes in such a manner as to display the contents of the box and especially designed for use in retail stores; and my object is more specifically to provide a device of this class of simple, durable, and inexpensive construction that may be folded for shipment or storage into a compact form and to occupy a minimum of space and to provide a device of this class that may be readily and quickly and easily adjusted to accurately fit boxes of various sizes.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device Whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustratedin the accompanying drawings, in which- Figure 1 shows the entire display-rack in perspective supporting a box, as in practical use. Fig. 2 shows a top or plan view of the rack and by dotted lines illustrating an adjusted position of the rack. Fig. 3 shows an enlarged detail view illustrating the means for connecting one of the uprights with the movable side piece. Fig. 4 shows an enlarged detail View illustrating the means for connecting the hinged brace with one of the supporting-legs.

Referring to the accompanying drawings, I have used the reference-numeral to indicate the stationaryside piece. This side piece is preferably made L shape in cross'section and having an end portion 11 at right angles to the body portion. Pivoted to the outer surface of the side piece 10 are two supporting-legs l2 and 13, the leg 12 being much longer than the other one. Pivoted to the leg 12 is a brace 14, having a slot 15 in its free end and a notch 16 in the top edge of the free end. Fixed to the leg 12 is a pin 17 and a gravity-lock 18. The brace 14 is firmly connected with the leg 12 by having the pin 17 Serial No. 69,600. (No model.)

admitted into the slot 15 and then permitting the lock 18 to enter the notch 16. The leg 13 is firmly supported by means of the additional brace 19, pivoted to the brace 14 and having a slot 20 in its end to receive a pin 21 on the lower portion of the leg 13.

Pivotally connected with the under surface of the side piece 10 are two cross-bars 21, and pivoted to the ends of the cross-bars 21 is the other side piece 22, also L-shaped in crosssection and materially shorter than the side piece 10. This side piece 22 is provided with a bolt 23, having a winged nut 24 thereon. A leg is provided with a longitudinal slot 26, and the bolt 23 is passed through this slot 26, and the winged nut 24 is placed on the bolt to engage the outer surface of the leg 25. By this means the leg is ad j ustably and pivotally connected with the side piece 22.

In practical use and assuming the device to be in position shown in Fig. 1, it is obvious that the adjustable rack will firmly and securely support abox against movement in any direction, because the side pieces 10 and 22 prevent its lateral movement, while the end piece 11 prevents longitudinal movement of the box. Assuming, further, that a box of less width is to be supported in the rack, it is obvious that it is only necessary to move the side piece 22 in the direction indicated by dotted lines in Fig. 2 until the said side piece engages the side of the box. Obviously as the side piece 22 is moved in this manner it will be necessary to adjust the supporting-leg 25 to position where it will support the side of the box resting on the part 22 in the same plane as the other side. Assuming that it is desired to fold the adjustable rack, the box is first removed, then the side piece 22 moved to a position parallel with the side piece 10. This may be done without the adjustment of screws or any other device, the sides being simply forced together. Then the leg 25 may be turned to a position parallelwith the side piece 22, and the lock 18 may be swung to an upward position, and then both the braces 14 and 19, as well as the legs 12 and 13, may be turned to a position parallel with the side piece 10, thus folding the adjustable rack into a very small space. It is obvious, further, that the device may be constructed very cheaply of thin metal bars and that they may be assembled very readily and quickly, and yet when in use they will firmly support the box in any desired position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is

1. An improved adjustable display-rack,

comprising in combination a side piece substantially L-shaped in cross-section and having an integral end piece at right angles thereto, supporting-legs pivoted to the outer surface of said side piece, a second side piece of shorter length than the first and also substantially L-shaped in cross-section, cross-bars pivoted to the under surfaces of the side pieces and a supporting-leg on the latter-mentioned side piece, for the purposes stated.

2. An improved adjustable display-rack, comprising in combination a side piece substantially L-shaped in cross-section and having an integral end piece at right angles to the side piece, flat bars pivoted to the under surface of the side piece, a second side piece shorter than the first also substantially L- shaped in cross-section and having said bars pivoted thereto, a supporting-leg pivoted to the outer surface of the longer side piece, a pin and a gravity-lock on said leg and the shorter leg pivoted to the other end portion of the outer surface of the longer side piece and having a pin thereon, abrace pivoted to the shorter leg and having a hook in its end to engage the said pin and a notch to receive the said gravity-lock, a brace-rod pivoted. to the first-mentioned brace and having a hook in its free end to engage said pin in the shorter leg, a lock having a longitudinal slot therein and a bolt passed through the short side piece and through the slot in said leg and a Winged nut in said bolt to engage the leg for the purposes stated.
